wifi: ath12k: fix memcpy array overflow in ath12k_peer_assoc_h_he()

Two memory copies in this function copy from a short array into a longer one,
using the wrong size, which leads to an out-of-bounds access:

include/linux/fortify-string.h:592:4: error: call to '__read_overflow2_field' declared with 'warning' attribute: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
                        __read_overflow2_field(q_size_field, size);
                        ^
include/linux/fortify-string.h:592:4: error: call to '__read_overflow2_field' declared with 'warning' attribute: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
2 errors generated.
